I know & have known a lot of dogs that are/were chained that are not & never were aggressive. Sure they are exposed to more cirumstances that may make them aggressive but the chain itself does not make them aggresive. So cagneydog if you knew anything at all about dogs you should know this.
And stop making assumptions before you know the facts, you can een see in he past pictures that there is more than 5 feet of chain, and it's not even a steel chain.

You can see that Roxy is cared for pretty well. In every picture I see grass not all dirt & have never seen any piles of poop either.

Granted it's still not right to chain a dog all the time but hey better than a lot of other circumstances that she could be in.

I do also agree that she should be spending less time on the computer & more time exercising Roxy.
